Detailed Description

Shape of an arrowhead matrix: a template argument of the compile-time solver, a function argument of the runtime one.

The dimension is n = border + block * blocks. ArrowheadStorageMap::valid checks a shape against a storage and a coupling.

Dimension of the matrix.

Returns

border + block * blocks

Member Data Documentation

coupling_row

int tdls::ArrowheadShape::coupling_row = 0

First border row coupled to the blocks, under the diagonal coupling (rows coupling_row .. coupling_row + block - 1). It stays 0 under the dense coupling.
